Serial Command Mode

Configuring Trigger Type
Serial command mode may be triggered by either software or hardware. Initially, you may use one
of the following configuration tools to set the trigger type: Network Enabler Administrator, Telnet
console, web console, or serial console.
The hardware trigger involves using DIO 0 to enter serial command mode. The software trigger
involves using a three-character sequence sent to the serial port to enter serial command mode. For
hardware versions 1.1 or earlier, when the SW Trigger is enabled, the highest achievable data
transmission rate will be reduced from 234000 bps to 55000 bps. This is because all data received
through serial port 0 will be parsed. In other words, the system must continuously check the serial
port data for the SW Trigger characters. This is not an issue for hardware versions 2.1 and later.
Network Enabler Administrator
To use Network Enabler Administrator to configure the trigger type, you will need to find the
module and open its configuration window. Please refer to Chapter 7 for additional details.
The trigger type will be configured under the
Serial CMD
tab. Check the
Modify
box in order to
make changes to the settings.
